Over-Run Alternator Decoupler (OAD) Pulley Inspection
Special Tools Required
Alternator OAD Pulley Holder 07AAB-TK8A100
- Remove the alternator (see ALTERNATOR REMOVAL AND INSTALLATION ).
- Clamp the alternator firmly in a vise.
- Remove the over-run alternator decoupler (OAD) pulley seal cap by piercing the center of the rubber cap with a flat screwdriver and prying it loose (see step 3 under Over-Run Alternator Decoupler (OAD) Pulley Removal and Installation
).NOTE: While the cap is off, the grease inside the OAD pulley is exposed. Do not wipe the grease off, and make sure it does not become contaminated.
- Insert the alternator OAD pulley holder into the OAD pulley (see step 4 under Over-Run Alternator Decoupler (OAD) Pulley Removal and Installation ).
- Place beam type torque wrench (A) with a 17 mm socket wrench (B) on the alternator OAD pulley holder.
- While holding the OAD pulley (C), rotate the alternator shaft counterclockwise. Make sure the alternator shaft is locked when applying the specified torque.
Specified Torque:
13 N.m (1.3 kgf.m, 10 lbf.ft)
- If the alternator shaft locks, go to step 7.
- If it does not lock, replace the OAD pulley (see OVER-RUN ALTERNATOR DECOUPLER (OAD) PULLEY REMOVAL AND INSTALLATION ).
- While holding the OAD pulley (A), rotate the alternator shaft clockwise. Check that the alternator shaft rotates at the specified torque or less.
Specified Torque:
0.8 N.m (0.08 kgf.m, 0.6 lbf.ft) max
- If the alternator shaft rotates at the specified torque or less, it is normal. Go to step 8.
- If it does not rotate at the specified torque or less, replace the OAD pulley (see OVER-RUN ALTERNATOR DECOUPLER (OAD) PULLEY REMOVAL AND INSTALLATION ).
- Install the new OAD pulley seal cap (see step 4 under Over-Run Alternator Decoupler (OAD) Pulley Removal and Installation ).
- Install the alternator (see INSTALLATION ).
